SHEET-DELIVERY APPARATUS.

SPECIFICATION forming part of Letters Patent No. 244,981, dated August2, 1881.

Application filed February 24, 1881.

.T 0 all whom it may concern: Be it known that I, JOHN J. CLAUSE, ofChicago, in the couutyof Cook and State of Illinois, have inventedcertain new and useful Improvements in Newspaper Folding Machines, ofwhich the following in a specification. I

My invention relates to improvements in devices in newspaper-foldingmachines for imposing each alternate sheet on top of the followingsheet, so that the two sheets may be folded simultaneously and by oneoperation; and my invention consists, in connection with a set ofcarrying-tapes, of a griping-cylinder arranged above the same andadapted to gripe each alternate sheet and carry it around the cylinderand deposit it upon the next succeeding sheet as the latter is carrieddirectly along on the tapes.

It also consists in the novel devices and com binations of devicesherein shown and described. The gripers on the griping-cylinder areoperated by means of an'oscillatingor movable eam, which changes itsposition at each alternate revolution of the cylinder, so as to. allowthe gripers to close upon the sheet at one revolution of the cylinderand to keep the same open to permit the next sheet to be carrieddirectly along on the tapes at the next revolution of the cylinder.

In the accompanying drawings, which form a part of this specification,and in which similar letters of reference indicate like parts,Figure 1is a cross-section of a device embodying my invention, showing themovable cam in position to permit the griping of the sheet as thegripers are carried around on the cylinder. Fig. 2 is a similar view,showing the movable cam in position to keep the gripers open to permitthe sheet being switched off the cylinder on top of the next followingsheet; and Fig. 3 is a plan view of same, the guides for keeping thesheets on the cylinder being removed.

I have thought it necessary to show only those parts of the foldingmachine to which my invention relates, as my improvement can be appliedto any ordinary folding-machine.

. In said drawings, A represents a portion of the frame of thefolding-machine. a is the (No model.)

underset of carrying tapes leading from the press to the first pair offolding-rollers. a is the upper set of tapes leadingfrom the press; anda is the upper set of tapes leading to the first pair offolding-rollers.

B is the griping-cylinder composed of short sections or separate pulleyssecured to the shaft B, which is mounted in suitable bearings in theframe.

The shaft 1), to which the gripers b are secured, is mounted in bearingsin the interior of the griping-cylinder, and is provided with a crank orarm, b carrying a friction-roller, W, on its end.

The gripers are held closed upon the cylinder by the torsion-spring bsurrounding the griper-shaft, and the same are opened in order to graspand to release the sheet by the movable or oscillating cam C, mountedloosely on the cylinder-shaft B, so as not to revolve with the cylinderacting upon the friction-roller 011 the arm of the griper-shaft. Thiscam C at each alternate revolution of the cylinder is made to occupy thepositions shown in Figs. 1 and 2, respectively, by means of the cam D,secured to the shaft d, acting upon the yoke or arm d attached rigidlyto the cam C. The

yoke d carries a friction-roller, d u on its P end, which is caused topress steadily against the face of the cam D by means of the spiralspring d one end of which is secured to the other end of the yoke d andits upper end to the frame.

The shaft d is geared to the cylindershaft by means of the gears 11 andd of such relative size that the shaft d makes one revolution while thecylinder-shaft makes two.

The form of the cam C is such that when occupying the position shown inFig. lit will cause the gripers to open and to close upon the sheet whenthe gripers are carried around with the cylinder to the position shownin dotted lines in the same figure. The form of the cam D is such and sotimed that at the second revolution of the cylinder it will cause thecam C to oscillate from the position shown in Fig. 1 to that shown inFig. 2, and thus cause the gripers to remain open from about theposition shown in dotted lines in Fig. 2 to that shown in solid lines,and thus at the same time permit the next succeeding sheet to passdirectly along on the tapes and to release and deposit the first sheetwhich has been carried around the cylinder upon such succeeding sheet.The cam D then permits the cam G to oscillate back to the position shownin Fig.1, so as to be ready to gripe the next alternate sheet and carryit around the cylinder.

G is a curved guide to keep the sheets on the cylinder.

H is a switch for switching the sheets oft the cylinder, secured to theshaft h., which is operated at each alternate revolution of the cylinderby means of the cam h secured to the shaft cl acting on the friction-roller [L2 on the arm of the switch-shaft It.

The cam It and the gears d and (Z are shown in dotted lines in Figs. 1and 2.

"What I claim is-- 1. The combination, with the deliveringtnpes, of thecylinderB, provided with gripers and mechanism, substantially such asdescribechfor actuating the gripers at the reccivlug-point at eachalternate revolution of the 1 3. The combination of thegriping-cylinder' provided with gripers with a movable gripercam and acam for moving the griper-caininto position to open the gripers andgripe the sheet at each alternate revolution of the cylinder, and intoposition for opening the gripers and discharging the sheet at the nextsucceeding revolution oi'thecylinder, substantially as specified.
